Adenomyosis is a kind of endogenous endometriosis, which is mainly manifested as dysmenorrhea, or increased menstrual flow, or infertility. For patients with adenomyosis, if there is no requirement for fertility in the clinic, and the state of anemia is caused by excessive menstruation, it is recommended to give surgical treatment, preferably hysterectomy. Depending on the condition of the cervix, either total or subtotal hysterectomy can be chosen. This surgery is best done within 3-7 days after menstruation because there is not much congestion in the pelvis at this time, so there will not be much intraoperative bleeding, which is a better time for surgery. If you have fertility requirements, it is recommended to put on the Mannix IUD to treat adenomyosis. The Mannix IUD should be put on two days after the menstrual period has not been cleared.
